[App_rpt-users] [Bulk] Issue with Hangup after first keying

[Bill South]

Joshua, I'm going to take a chance here and state what seems to be the obvious; all your additional work to get your node functional seem to stem from the rather unusual radio you are using.  So why not just bite the bullet and change radios to something a bit more standard, like a ham dual-band FM radio for some flexability, or maybe a ham monoband HT or mobile radio to save both time and money?  Seems the time and effort you have put into getting the AM aircraft radio to function would be moot with just about any ham FM radio replacing it.  And if you get one with a data-access conection, all the signals you need are there so you can run COR or stratight audio relatively easily, whatever your choice?  Or have I missed something obvious related to your choice of radios?  Just a thought.

Thanks Ben for the quick feedback. I think I might have figured it out. It turns out my COR signal might not necessarily be the best COR signal. It looks like the signal goes high on BOTH RX and TX. This is probably causing asterisk to think its receiving when its sending getting into a nice infinite loop.

I'm going to try an AND gate with the PTT so that PTT has to be high (i.e. NOT TX) and speaker mute (my COR) has to be high for a true COR output on RX.

In the meantime I tried carrierfrom=vox but it didn't really seem to work. Anybody get this working properly?

Thanks,

Josh

sounds to me you are using a simplex node.

In your simpleusb.conf or usbradio.conf, ensure duplex=0, and not
duplex=1. This is different from duplex= in rpt.conf

I had the same symptoms when I first setup my node.

Also, make sure you use the radio-tune-menu with a service monitor or
some other methods to make sure your have good, clean audio being
transmitted over the internet and over your node radio.
